Turned Flush/paired board

[SammySlim]

This is my first post for advice in this forum; apologies if this seems standard or worse ... lol Live tournament, $500 buyin, 5k starting stacks. 100/200 blinds, no antes yet.

I have been tight and aggressive, shown down mostly good hands. Have not shown down anything out of line, although I have made a few moves on passive players. Table has been relatively passive, folding to CBs mostly (hence I've made them frequently but not always). Villain has been solid, seeemed LAG early but recently settled down. He has shown down only a few hands but they were mixed between high cards, small pairs and SCs.

Hero has Th9h in the CO, stack is 10,500, average stack is probably 7k-8k. Villain is on the button with 11k.

Folds to me. I raise to 600. Villain calls, blinds fold. 1500 in the pot.

Flop: 7h 3h 7d

Hero bets 800. Villain pauses, then calls. 3100 in pot.

Turn: Ah. Completes my flush.

Hero bets 2400. Villain tanks again, then calls. Hmmm. Pot is 7900. My stack is now 6700.

River: blank.

Hero?

Comments on all streets are welcome. Should I have c/r the turn? bet smaller on the turn? (which is what I think in hindsight, perhaps 1500 or maybe even less). River shove? River c/r? River c/c (including a shove?). Different play online vs. live?

Thanks in advance.
